CUTTING-MACHINE.

Application filed June 22, 1909.

Specification of Letters Patent. Patented Dec. 28, 1909.

Serial No. 503,596.

To all whom it may concern:

Be it known that I, PIERRE E. J AOCARD, a citizen of Switzerland,residing at Camden, in the county of Camden and State of New Jersey,have invented certain new and useful Improvements in Cutting-Machines,of which the following is a specification.

My invention relates to an improved cutting machine, which is designedprimarily for cutting out patterns and designs in curtains and the like,the object of the invention being to provide improvements of thischaracter, which will not only facilitate the cutting out of designs andpatterns, but will result in a better manufacture at a reduced cost.

Heretofore patterns in curtains have been almost uniformly cut out byhand with shears, and as the work, in order to be at all profitable,must be done rapidly, or as rapidly as can be done by hand, the resulthas been in a great many instances, badly cut patterns.

The invention consists in certain novel features of construction, andcombinations and arrangements of parts as will be more fully hereinafterdescribed and pointed out in the claims.

In the accompanying drawings, Figure 1, is a view in elevationillustrating my improvements. Fig. 2, is a top plan view. Fig. 3, is aview in longitudinal section. Fig. a, is a view in cross section on theline H of Fig. 3. Fig. 5, is a view in section on the line 5-5 of Fig.3. Fig. 6, is a view in section on the line 66 of Fig. 3. Fig. 7, is aView in longitudinal section of a modified form of my invention, andFig. 8, is a view in elevation partly in section at right angles to Fig.7.

1 represents a supporting base or table, 2 an upright thereon, and 3 .alever or frame pivotally supported between its ends on trunnions 4connected to the upper end of upright 2, and having a weight 5 at oneend to counterbalance the device, as will more fully hereinafter appear.

The lever or frame 3 is preferably of the open work form, in which aseries of bearings 6 are provided for a shaft 7, upon which latter abeveled gear 8 is secured, and this shaft may be driven by a belt 9passing around a pulley 10 on the shaft, and driven from any source ofpower.

A short shaft stub 11 located at right angles to shaft 7, has an openingto receive 'the shaft to permit pivotal movement of the stub 11 on shaft7. A beveled gear 12 loose on shaft 11 is driven by gear 8, and aneccentric 13 is locked to turn with gear 12, and turned within aneccentric strap 14 to reciprocate a rod 15, as will hereinafter appear.This rod reciprocates in a tube 16, the latter having a perforated ear17 at its upper end, pivotally supported upon the stub 11.

The tube 16 is provided with an internal enlargement 17 having arestricted opening or passage 18 to guide rod 15 in its reciprocation,and center the latter. This enlarged or heavier portion 17 of tube 16,is made with an annular groove 19, into which lugs 20 at the inner endsof screws 21 project, said screws being projected into and through asleeve 22, which permits the sleeve free turning movement onthe tube 16.

I11 the lower end of sleeve 22, a foot piece 23 is secured in anyapproved manner, and is provided with an opening 24, through which thecutting plunger 25 is reciprocated by rod 15, and this foo-t portion iscut out as at 26 to receive the goods, and allow the cutter to be movedabout as may be necessary to cut out the pattern.

The lower end of plunger 25 is inclined or beveled as shown, so that thecutting operation is thereby facilitated, and begins at least, at thesame point of each stroke of the plunger. This plunger 25 is connectedwith a block or head 27 mounted to reciprocate in sleeve 22, andrecessed as at 28 to receive a head 29 on rod 15, and connect the head27 and rod, and permit free turning movement of the head on the rod.

In order to prevent rotary movement of head 27 in sleeve 22, the head ismade with a flat recess .as at 30., and a flat block or key 31 issecured in an opening in sleeve 22, and is located adjacent theflattened recess 30 of head 27, and while it permits free reciprocationof the head, will prevent any rotary movement of the head within thesleeve.

The operation is as follows: The goods to be out are passed into the cutout portion 26 of the foot 23, and as the plunger 25 is reciprocated byrod 15, and the transmitting mechanism above described, the operatorholding sleeve 22 can turn the same and move the machine about, so as toexactly follow the pattern and accurately cut out the design.

In themodification illustrated in Figs. 7

and 8, instead of employing a reciprocating.

cutting plunger, I have illustrated a rotary cutter as shown at' 32,'driven'by beveled gears 33 and 34, and located in the lower end of asleeve 35, which latter is provided with screws 36, projecting into agroove 37 in a-tulo'e 38, so that this sleeve 35 may act as a handle toallow the cutter to be manipulated as may be desired. The gear 34: issecured upon vertical shaft 39 in sleeve 35, and tube 38, and may bedriven by a pulley l0, or other desired means.

Other slight changes might be made in the general form and arrangementsof parts described without departing from my invention, and hence I donot restrict myself to the precise details set forth, but considermyself at liberty to make such changes and alterations as fairly fallwithin the spirit and scope of the claims.

. Having thus. described my invention what' I claim as new and-desire tosecure by Letters Patent is .sleeve for reciprocating said cutter and 1.In a machinev of the character described, the combination with a tube, asleeve mounted to turn around the tube, a cutter in said sleeve, meansin said tube and means in said tube preventing rotary movement of thecutter operating means.

2. In a machine of the character described, the combination with a tubehaving an annular groove therein, a sleeve around the tube, screws inthe sleeve projecting into the groove in the tube, a cutter at the'lowerend of said sleeve, means in said tube and sleeve for operating saidcutter, and'means in said tube preventing rotary movement of the cutteroperating means.

3. In a machine of the character described, the combination with a tube,a sleeve mounted to turn on the tube, a cutvting plunger in said sleeve,a reciprocating rod connected to said plunger, and means for preventingrotary movement of the plunger in the sleeve. I

4. In a machine of the character described, the combination with a tube,a

...connected to said plunger, and a key in said sleeve engaging theplunger, and'preventing rotary movement 'of'the plunger in the sleeve.

5(In a machine of the character described, the combination with atubehaving an annular groove, a sleeve on said tube,

foot in said sleeve, a cutting plunger in said sleeve, a head on saidplunger having arecess, a reciprocatlng rod, a head on said rod in saidrecess, means for preventing rotary movement of said head in saidsleeve, an eccentric, and an eccentric strap around said eccentric andsecured to said rod.

' 7. In a machine of the character described, the combination with abase, an up right thereon, a lever pivoted between its ends on saidupright, a weight on one end of said. lever, a shaft supportedlongitudinally in said lever, a drive pulley on said shaft, a pinion onsaid shaft, a shaft stub at right angles to said shaft and supportedthereby, a pinion on said stub in mesh with the pinion on the shaft, aneccentric turned by said pinion on the stub, a tube supported on saidstub, a rod in said tube, an eccentric strap secured to said rod andmounted around said eccentric, a sleeve mounted to turn on said tube,and a reciprocating cutting plunger in said sleeve connected to. saidrod.

In testimony whereof I have signed my name to this specification in thepresence of 7 two subscribing witnesses.
